Description

Mold asset location control and production management system using unique pattern of mold

The present invention relates to a mold asset location control and production management system using a mold's unique pattern, and more particularly, to prevention of theft through monitoring the location of mold assets and information related to mold use status such as the number of punches and movement of molds. It relates to a mold asset location control and production management system using a unique mold pattern to manage production efficiency by enabling collection and transmission of

A mold refers to a device used to give a desired shape or shape to a material such as plastic or metal.

Molds are currently used by almost all manufacturers, and the company requesting mold production wants history management of the actual mold, integrated management of mold information made by various mold manufacturers, and mold quality control.

However, it is difficult to grasp the current status of molds in real time because multi-level mass production companies store molds on their own, and it is difficult to determine the size of products to be mass-produced using molds due to insufficient history management of molds.

In addition, product reliability is degraded due to insufficient management of mold injection conditions by mass-producers.

If you explain in detail the current mold history and real-life management operation method, the mold-related information is recorded by the worker in charge of the mold production by directly inputting it into the system.

In addition, it is a method in which the person in charge records mold-related information in the system through direct input into the system when a mold is brought in or out from a mass-production company, a mold modification company, or a mold disposal company.

However, in this method, it is impossible to make a mold and check information about the mold if the mold maker's operator does not directly input the system.

This is the same problem for mass-producers, mold repair companies, and scrap companies.

In addition, since there is no integrated system from the mold maker to the scrapping company, it is difficult for the mold maker or mass-producer to figure out how much a particular mold is currently being used.

Due to these circumstances, there has been a demand for a method and system capable of facilitating mold history and actual management of molds by managers of mold manufacturers, mass-producers, mold modification companies, and scrapping companies.

In addition, there is a need to integrate mold information, which is currently distributed and managed by several companies.

As a prior art data, Korean Patent Registration No. 10-1260721 discloses technical information about an RFID-based mold management method using a smart device.

The RFID-based mold management method using a smart device according to the prior art uses an RFID tag in a technical aspect, so information manipulation and input mistakes can be prevented, and a safety device is added to the tag after the initial encoding, so information cannot be changed later. By excluding user input, the possibility of information error due to input mistakes can be prevented in advance.

In addition, in terms of management, it is possible to determine whether the information on the actual holding of mold assets through RFID matches the information on the system, enabling consistent mold history management and securing the reliability of the current location and condition of molds by the mold status board. It is possible to manage the exact location of mold storage and check real-time mold information using smart devices, reduce the time required for mold export and import, and protect mold assets through mold location information. Design leakage is prevented, and in the event of mold asset loss, the location of responsibility for mold loss can be identified.

In terms of economy, since injection is performed by loading the injection conditions provided by the system, quality reliability is secured, real-time response to various orders is possible, and manual work is reduced, so productivity and product quality can be improved.

In this way, the RFID-based mold management method using a smart device according to the prior art is for companies that manufacture molds or produce parts or products using molds to manage mold production for the production of the mold itself, and injection molding using molds. It is comprehensively performing mold usage management, mold asset management for mold maintenance, and mold history management.

However, in the case of mass production companies that produce parts or products using molds, the number of punches that can be punched is determined depending on the deterioration state of the mold exposed to heat for a long time, but the number of punches is not properly managed. limits may be exceeded.

In this way, a mold whose number of punches exceeds the limit may cause a press to fail to operate, and there is a problem in that the quality of a single product decreases or the defect rate increases.

In addition, there is a problem in that inventory management of small items necessary for preserving the mold is not performed, which may cause cost management of consumables or inventory shortage of consumables.

On the other hand, with the current mold management and supervision, practical management and supervision cannot be performed after the mold is delivered to affiliates, and even if theft occurs, it is impossible to find out the leakage route or location, so it is impossible to respond appropriately to mold leakage. am.

On the other hand, information on how subsidiaries are operating molds delivered becomes an important point in mold management and supervision.

In particular, the number of strokes is a clue showing whether the mold is in operation, and may further include a number of strokes measurement unit to provide a function of measuring the number of strokes.

That is, the stroke count measurement unit 170 performs a function of detecting the number of mold punches and the production status by using the unique motion pattern of the mold.

It is characterized by providing the necessary power supply to the mold asset management terminal through a power generation module including any one of contact type, non-contact type, mechanical type, and electric/electronic type by using the unique motion characteristics and impact characteristics of the mold.

Specifically, a power generation module for power supply or battery charging required for a mold asset management terminal may be added in the stroke number measuring unit in a contact or non-contact manner using the unique motion characteristics and impact characteristics of the mold.

That is, whenever the press reciprocates, the number of strokes is measured using a mechanical or electrical signal and an acceleration sensor through the power generation module.

As for the measurement method, for example, the number of strokes can be measured using an acceleration sensor and a mechanical or electrical signal generated from a self-generating module whenever the press reciprocates.

At this time, if an algorithm for determining whether the device is operating using acceleration is installed, the number of strokes can be accurately measured through this.

On the other hand, as shown in FIG. 5, the stroke measurement unit 240,

Specifically, as shown in FIG. 4, when the first mold asset management terminal 200 operates in standby mode and presses the push switch formed on the mold asset management terminal 200 continuously for 3 seconds or more, it enters sleep mode by init report. will convert

Thereafter, when an impact is sensed by the acceleration sensor, the sleep mode is converted into a wake-up mode by the operation of the wake-up conversion unit when a set period of time elapses.

At this time, an event signal is generated by obtaining an acceleration value sensed from the acceleration sensor when the wakeup mode is converted by the wakeup conversion unit through the event detector, and it is determined whether movement and detachment are detected.

If movement and detachment are detected, an even report is generated and provided to the wakeup conversion unit to perform continuous sensing.

And, the event detecting unit provides a periodic report to the sleep mode conversion unit when time as much as the period elapses.

In addition, when the event detecting unit acquires the shock detection signal a set number of times or more in the sleep mode, it provides a stroke count measurement signal to the shock mode executing unit.

Accordingly, when the shock mode executing unit acquires the event signal generated by the event detecting unit, the number of strokes is measured if the shock detection signal is equal to or greater than the set number of times in the sleep mode.

For example, if the shock is sensed 10 times or more in the sleep mode, it is switched to the shock mode, and the change in number of strokes is measured in the shock mode.

In general, checking the number of strokes in sleep mode consumes considerable power, causing a problem of having to replace the battery within a short period of time. It offers the advantage of reducing

In addition, as shown in FIG. 6, the actual mold hitting acceleration measurement result is shown through the stroke measurement unit, and in the case of actual stroke detection, the amplitude is much larger than usual, so the number of strokes can be measured based on the amount of change in amplitude. .
